摘要

我们研究了一般类型表面模量空间的Kollár–Shepherd-Barron–Alexeev（KSBA）紧致化中发生的某种虫洞现象。它的出现是因为在KBSA边界上的表面中出现了特定的极值P分辨率。我们陈述了一个一般的虫洞猜想，并在广泛的情况下证明了它。最后，我们讨论了一些拓扑性质和有待解决的问题。

On wormholes in the moduli space of surfaces

We study a certain wormholing phenomenon that takes place in the Kollár–Shepherd-Barron–Alexeev (KSBA) compactification of the moduli space of surfaces of general type. It occurs because of the appearance of particular extremal P-resolutions in surfaces on the KBSA boundary. We state a general wormhole conjecture, and we prove it for a wide range of cases. At the end, we discuss some topological properties and open questions.
